We meet our ill-tempered protagonist—the story’s titular “brat”—at a low moment, but not yet at rock bottom. The Gabriel of the novel is mourning the death of his father as well as a recent breakup, and struggling to finish writing his second book. Alone and aimless, he agrees to move back into his parents’ house to clear it out for sale. Here, the clichés end.
Gabriel has trouble delivering on his promise as the moldy, overgrown house deteriorates around him, so does his own health, and large sheets of his skin begin to peel from his body at a terrifying rate. In fragments and figments, Gabriel takes us on a surreal journey into the mysteries of the family home, where he finds unfinished manuscripts written by his parents which seem to mutate every time he picks them up, and a bizarre home video that hints at long-buried secrets.
